| 8 | HLA-C端粒端150kb区域与犹太人群银屑病相关显示文摘The HLA-Cw 0602 has been associated with psoriasis in different ethnic groups. But, it remains unclear whether HLA-C is the PSORS1 gene (the psoriasis gene in the MHC). Thus, several case-control studies have been performed in order to investigate whether HLA-C itself determines the susceptibility to the disease. We studied 59 Jewish patients with type I psoriasis and 79 matched controls. Polymorphic genes and markers from HLA-B (centromeric to HLA-C) to the corneodesmosin (CDSN) gene (telomeric to HLA-C) were genotyped in order to determine their contribution to the susceptibility to psoriasis. Neither HLA-Cw 0602 nor the allele CDSN TTC were significantly associated with psoriasis with the size of the sample studied. The genes and markers telomeric to HLA-C such as the microsatellite C1-4- 4 (OR = 2.6, 95% CI = 1.4- 4.7, Pc =0.018) the octamer transcription factor (OTF)- 3 gene (OR = 2.6, 95% CI = 1.6- 4.3, Pc = 0.0001) and the α -helix coiled-coil rod homologue (HCR) gene (OR = 2.5, 95% CI = 1.3- 4.5, Pc = 0.004), however, were associated with the disease. These results suggest that a major psoriasis susceptibility gene is likely to be located within a region of 150 kb telomeric to HLA-C and centromeric to the CDSN gene. | jewish population Martnez-Borra J.
